LLVM seems to be generating way too complex of branching based on the short-circuit optimization. The code in question is as follows: define void @ test_fc_while_and(float %x, float %y, float addrspace(11)* %result) nounwind { entry: %tobool3 = fcmp une float %x, 0.000000e+000 ; <i1> [#uses=1] %tobool24 = fcmp une float %y, 0.000000e+000 ;

I am trying to give a quota of how many instructions can be run to a program. So create a simple function as below: define void @add_gas(i64 %gasCost) { __virtual_entry: %0 = load i64, i64* @__WAVM__XX__gGasUsed ### I am sure it exists, same as the __WAVM__XX__gGasLimit %addtmp = add i64 %0, %gasCost %1 = load i64, i64* @__WAVM__XX__gGasLimit %cmptmp = icmp sgt i64 %addtmp, %1 br i1

Hi, I am sorry for this simple question, but... How do I extract something from a data.frame? The following is my Problem: I have got a dataframe "a" with various columns. One of those columns is called V3 and contains elements of the following levels: > levels(a$V3) [1] "C" "CA" "CB" "CD" "CD1" "CD2"

Dump the IR before newgvn and run through opt -newgvn. It should crash. I'm not familiar with your frontend but you might want to use -mllvm -opt-bisect-limit.

When zig updated to llvm 5 we started hitting this assertion: zig: /home/andy/downloads/llvm-project/llvm/include/llvm/Support/Casting.h:106: static bool llvm::isa_impl_cl<To, const From*>::doit(const From*) [with To = llvm::Instruction; From = llvm::Value]: Assertion `Val && "isa<> used on a null pointer"' failed.

Can you please open a bug on bugzilla and attach the ir testcase? Your fix doesn't look right (just hiding the assertion failure) On Sep 17, 2017 10:45 AM, "Andrew Kelley via llvm-dev" < llvm-dev at lists.llvm.org> wrote: > What do you think about this patch? > > --- a/llvm/lib/Transforms/Scalar/NewGVN.cpp > +++ b/llvm/lib/Transforms/Scalar/NewGVN.cpp > @@

So, 90% of the time I've seen this, it was memory corruption, usually use after free. I know I fixed one after 5.0 branched. You should compile with address sanitizer enabled, and I suspect you will find the issue quicky. If not, we really need ir that reproduces it.

That's correct. Use AT&T asm printer and GNU as everywhere. Everything else is too weak to be usable and thus one should consider intel asm printer to be of "listing quality". -- With

Thanks for Anton's reply. Does anybody have an idea of roughly how much effort is required to make intel asm printer to be usable? If it is within weeks, probably I can give it a try.

Hi, I've encountered the following problem at a client. The problem results in one or more of the smbd processing continuously grabbing more and more memory until the system runs out of memory or just becomes unusable due to a low memory condition. This error is extremely serious as the entire server is eventually brought down by one error. After debugging this error at the

Hi all, With this series of patches, you can determine the owners of any type of I/Os. I ported the previous version to linux-2.6.26-rc2-mm1. This makes dm-ioband -- I/O bandwidth controller -- be able to control the Block I/O bandwidths even when it accepts delayed write requests. Dm-ioband can find the owner cgroup of each request. It is also possible that OpenVz team and NEC Uchida-san team

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
